Morphology and anatomy of the Cordia trichotoma (Vell.) Arrab. ex I. M. Johnst diaspore (Boraginaceae)
Souza, Luiz Antonio de;
Brazilian Archives of Biology and Technology , 2008, DOI: 10.1590/S1516-89132008000400014
Abstract: this study analyzed the morphology and anatomy of the cordia trichotoma (vell.) arrab. ex i. m. johnst diaspore. the objectives were: the structural analysis of the calyx and corolla that persisted in the ripe fruit and acted in the anemocoric dispersion process; the vascularization of the gynoecium for better understanding of the carpel/locule number of the ovary; nectary structure; and the anatomical analysis of the developmental pericarp and seed for better definition of the fruit type. the results showed that the perianth had aerenchyma and the ovary was 2- 4- locule forming endothelium and false septum. the fruit was drupoid nuculanium and the seed was exotestal.
A representa??o das múltiplas dimens?es paradigmáticas no estudo da administra??o: um ensaio sobre os limites contidos nas defesas paradigmáticas excludentes

Revista de Administra??o Contemporanea , 2011, DOI: 10.1590/S1415-65552011000200003
Abstract: discussion of paradigms governing the production of knowledge in administration, whose characteristics deal with objects and concepts of high complexity, shows evidence that many of its panelists lose significant parts of the question by engaging in the defense of one particular paradigm. taking the question - do the limitations inherent to the epistemological paradigm employed in administration research issues permit polarized discussions, or is the problem more complex than what is sustained by isolated visions of each paradigm? - as a basis, the aim of this essay is to show that the theoretical paradigms complement each other and that none of these can be abandoned because of their incompleteness. the focus differs from the positivist paradigm superiority, as noted in donaldson (1997) and alvesson (1995), or from dichotomous contrasts and exclusive oppositions, as in the work of tadajewski (2009). the positivist, interpretative, and critical paradigms are explained and contrasted with analogies with physics, the limitations imposed by the knowledge provided by the latest linguistics studies, hypercubes that mark the data mining technique, and studies of emerging phenomena in complex systems. the general approach is the exploration of an ontological gap created by exclusionary debates concerning paradigms.

Abstract: Discussion of paradigms governing the production of knowledge in administration, whose characteristics deal with objects and concepts of high complexity, shows evidence that many of its panelists lose significant parts of the question by engaging in the defense of one particular paradigm. Taking the question – Do the limitations inherent to the epistemological paradigm employed in Administration research issues permit polarized discussions, or is the problem more complex than what is sustained by isolated visions of each paradigm? – as a basis, the aim of this essay is to show that the theoretical paradigms complement each other and that none of these can be abandoned because of their incompleteness. The focus differs from the positivist paradigm superiority, as noted in Donaldson (1997) and Alvesson (1995), or from dichotomous contrasts and exclusive oppositions, as in the work of Tadajewski (2009). The positivist, interpretative, and critical paradigms are explained and contrasted with analogies with Physics, the limitations imposed by the knowledge provided by the latest Linguistics studies, Hypercubes that mark the Data Mining technique, and studies of emerging phenomena in complex systems. The general approach is the exploration of an ontological gap created by exclusionary debates concerning paradigms.

Indicadores de sustentabilidade na Reserva de Desenvolvimento Sustentável do Piranha, Manacapuru, Amazonas, Brasil
Andrade, Antonio Luiz Menezes de;
Acta Amazonica , 2007, DOI: 10.1590/S0044-59672007000300011
Abstract: the indicators are qualitative and quantitative information, used to decide processes in all the levels of the society. in this direction the intention of this study is to comparatively evaluate the ways of life of the traditional populations of the studied area from capitals: human, social, natural, physical and financial, and to consider indicators of evaluation and monitoring to protected areas of the amazon. the empirical base for the work were nine agricultural communities of the piranha development reserve, being three of them from the sustainable use zone and six of them from the damping zone north and south in manacapuru-am. the methodology procedure adopted in the inquiry is quantitative. the data were collected, through the action oral stories, participant observations, structuralized and semi-structuralized interviews, informal colloquies and secondary data. the collected data were organized by capitals and later used in the comparison of the indicators and construction of a local sustainable development index - lsdi. the obtained results have demonstrated a better development of the ways of communitarian life in the communities of the sustainable use zone, with prominence for the financial capital. the lsdi constructed has showed a representative local reality, of ease application, efficient to measure the performance of the integrant indicators of the capitals. in this way, directions are pointed to take decisions in agreement with the principles of the sustainability and recommendations of global agenda 21.
Um século de cólera: itinerário do medo
Santos, Luiz Antonio de Castro;
Physis: Revista de Saúde Coletiva , 1994, DOI: 10.1590/S0103-73311994000100005
Abstract: the comparative method is one of hístorical sociology's indispensable tools. focusing on a century of cholera epidemics in a numbcr of countries, the present comparative study endeavors to show how one same historical-social phenomenon displays sharp contrasts across time and space in the impacts il has on culture, society, and poliíics. for example, dissimilar state-building processes have left deep marks on lhe nature of administra-tive apparatuses in different countries, leading each nation to develop its own distinct forms of sanitary organizations and its own ways of combaling cholera cpidemics. at the same lime, historical comparative analysis makes it possiblc to pick out patterns of rclationship between illness and society within thcse differentiated contexts. despite their differences, in various national communities the ethical values, beliefs, and behavior patterns that social classes, the medicai profession, religious groups, and government administrations have displayed towards cholera reveal certain practically invariable symbolic patterns. comparative analysis' madc it possible, for example, to detect that in the mid-nineteenth century everyone in rio de janeiro as well as in new york saw cholera as a punishment from god, a disease which struck first at those whose social behavior was "censurabie". there is a twofold purpose in this arlicle's narration of the human tragedy of the new york experience with cholera: (1) to show how a sociology of evereyday life can reveal complex interactions between illness, individual, and society in a nineteenth-century metropolis and (2) to show how the analysis of a different historical experience - in this case, the united states - can uncover strong contrasts and similarities with brazil. such knowledge of another reality is a challenge in learning how the brazilian population has faced this epidemic disease. in terms of the disease's macro-historical effects, rising death rates had a less brutal impact than socia
O princípio da universaliza??o em Rawls e Habermas: uma avalia??o crítica
Lima, Luiz Antonio de Oliveira;
Revista Direito GV , 2011, DOI: 10.1590/S1808-24322011000100012
Abstract: the aim of this paper is to present an analysis of the so called principle of the universalization as it appears in the works of john rawls and jürgen habermas. the universal is a revered concept in almost all societies as far as it means a prevalence of the general interests over the particular ones. it prevails under certain historical conditions when the less privileged classes have access to some of the patterns of life of the upper classes. this ascent however has a negative counterpart: the intellectual elites present the norms that must rule through an abstract discourse preventing those that do not have access to this form of symbolic capital to benefit from the new circumstances. this work will try to show that the works of rawls and habermas may be characterized as this form of abstract universalization.
Metas inflacionárias: a análise convencional e um modelo alternativo
Lima, Luiz Antonio de Oliveira;
Revista de Economia Política , 2008, DOI: 10.1590/S0101-31572008000200001
Abstract: inflation targeting: the conventional analysis and an alternative model. this article has two aims: the first one is to present a formal model of the monetary policy identified generally as "inflation targeting policy", an instrument of intervention of the central bank, through the short run nominal interest rate. the second aim is to discuss and criticize the theoretical assumptions of the model specially the concepts of "natural rate of interest" and of potential product presented by the "augmented philips curve"; and to present a more realistic control of inflation targeting which does not assume the hypotheses above, and in which inflation targeting is based on the control of real rate of interest.
